# Health Data Set

import pandas as pd

health_data = pd.read_csv(“Documents/Data Science/data2.csv”, header=0, sep=”,”)

print(health_data.to_string())

Plot the Existing Data in Python

Now, we can first plot the values of Average_Pulse against Calorie_Burnage using the matplotlib library.

The plot() function is used to make a 2D hexagonal binning plot of points x,y:

import sys

import matplotlib

%matplotlib inline

import pandas as pd

import matplotlib.pyplot as plt

health_data = pd.read_csv(“Documents/Data Science/data2.csv”, header=0, sep=”,”)

health_data.plot(x =’Average_Pulse’, y=’Calorie_Burnage’, kind=’line’),

plt.ylim(ymin=0)

plt.xlim(xmin=0)

plt.show()

Example Explained

Import the pyplot module of the matplotlib library

Plot the data from Average_Pulse against Calorie_Burnage

kind=’line’ tells us which type of plot we want. Here, we want to have a straight line

plt.ylim() and plt.xlim() tells us what value we want the axis to start on. Here, we want the axis to begin from zero

plt.show() shows us the output

The Graph Output

As we can see, there is a relationship between Average_Pulse and Calorie_Burnage.

Calorie_Burnage increases proportionally with Average_Pulse.

It means that we can use Average_Pulse to predict Calorie_Burnage.

Why is The Line Not Fully Drawn Down to The y-axis?

The reason is that we do not have observations where Average_Pulse or Calorie_Burnage are equal to zero.

80 is the first observation

of Average_Pulse and 240 is the first observation of Calorie_Burnage.

We can use the diagonal line to find the mathematical function to predict calorie burnage.

As it turns out:

If the average pulse is 80, the calorie burnage is 240

If the average pulse is 90, the calorie burnage is 260

If the average pulse is 100, the calorie burnage is 280

There is a pattern. If average pulse increases by 10, the calorie burnage increases by 20.
